At present hiv infection rate south africa minipress 2.5 mg with amex, not more than one-third of patients with confirmed osteomyelitis are likely to need an operation and the percentage is decreasing; adults with vertebral infection seldom do hiv lung infection symptoms minipress 2.5bottles purchase without prescription. Simple skin traction may suffice and hiv infection lawsuit discount 2mg minipress otc, if the hip is involved late hiv infection symptoms purchase minipress 2.5mg without a prescription, this also helps to prevent dislocation hiv infection rates in california buy discount minipress online. At other sites a plaster slab or half-cylinder may be used, but it should not obscure the affected area. Analgesics should be given at repeated intervals without waiting for the patient to ask for them. Septicaemia and fever can cause severe dehydration and it may be necessary to give fluid intravenously. Complications A lethal outcome from septicaemia is nowadays extremely rare; with antibiotics the child nearly always recovers and the bone may return to normal. But morbidity and sequelae are common, especially if treatment is delayed or the organism is insensitive to the chosen antibiotic. Epiphyseal damage and altered bone growth In neonates and infants whose epiphyses are still entirely cartilaginous, metaphyseal vessels penetrate the physis and may carry the infection into the epiphysis. If this happens, the physeal growth plate can be irrevocably damaged and the cartilaginous epiphysis may be destroyed, leading to arrest of growth and shortening of the bone. At the hip joint, the proximal end of the femur may be so badly damaged as to result in a pseudarthrosis. Suppurative arthritis this may occur: (1) in very young infants, in whom the growth plate is not an impenetrable barrier; (2) where the metaphysis is intracapsular, as in the upper femur; or (3) from metastatic infection. In infants, it is so common as almost to be taken for granted, especially with osteomyelitis of the femoral neck. Ultrasound will help to demonstrate an effusion, but the definitive diagnosis is obtained by joint aspiration. Metastatic infection this is sometimes seen ­ generally in infants ­ and may involve other bones, joints, serous cavities, the brain or lung. Secondary infection sites are easily missed when attention is focused on one particular area; it is important to be alert to this complication and to repeatedly examine the child all over. Pathological fracture Fracture is uncommon, but it may occur if treatment is delayed and the bone is weakened, either by erosion at the site of infection or by overzealous debridement. Chronic osteomyelitis Despite improved methods of diagnosis and treatment, acute osteomyelitis sometimes fails to resolve. Weeks or months after the onset of acute infection, a sequestrum may appear in the follow-up X-ray and the patient may develop a chronic infection and a draining sinus. This may be related to late or inadequate treatment but is also seen in debilitated patients and in those with compromised defence mechanisms. The cavity is lined by granulation tissue containing a mixture of acute and chronic inflammatory cells. Occasionally it appears in the epiphysis and, in adults, in one of the vertebral bodies. Clinical features the patient is usually a child or adolescent who has had pain near one of the larger joints for several weeks or even months. He or she may have a limp and often there is slight swelling, muscle wasting and local tenderness. Most often it is seen in the tibial or femoral metaphysis, but it may occur in the epiphysis or in one of the cuboidal bones. Metaphyseal lesions cause little or no periosteal reaction; diaphyseal lesions may be associated with periosteal new bone formation and marked cortical thickening. Its relative mildness is presumably due to the organism being less virulent or the patient more resistant (or both). Its skeletal distribution is more variable than in acute osteomyelitis, but the distal femur and the proximal and distal tibia are the frequent sites. If fluid is encountered, it should be sent for bacteriological culture; this is positive in about half the cases and the organism is almost invariably Staphylococcus aureus. Immobilization and antibiotics (flucloxacillin and fusidic acid) intravenously for 4 or 5 days and then orally for another 6 weeks usually result in healing, though this may take up to 12 months. If the diagnosis is in doubt, an open biopsy is needed and the lesion may be curetted at the same time. Curettage is also indicated if the X-ray shows that there is no healing after conservative treatment; this is always followed by a further course of antibiotics. X-ray appearances may be more difficult than usual to interpret because of bone fragmentation. Microbiological investigation If the wound is infected, a wound swab should be examined and cultured for organisms which can be tested for antibiotic sensitivity. Unfortunately, though, standard laboratory methods still yield negative results in about 20% of cases of overt infection. Routine wound swabs of open fracture wounds in the absence of infection is not recommended as cultured organisms are very unlikely to be the same as the organism causing any subsequent infection. Multiple tissue samples taken with clean, sterile instruments are preferred for microbiological investigations. The combination of tissue injury, vascular damage, oedema, haematoma, dead bone fragments and an open pathway to the atmosphere must invite bacterial invasion even if the wound is not contaminated with visible particulate dirt. Staphylococcus aureus is the usual pathogen, but other organisms such as Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa are sometimes involved. Occasionally, anaerobic organisms (clostridia, anaerobic streptococci or Bacteroides) appear in contaminated wounds. Treatment the essence of treatment of open fractures is prophylaxis of infection: thorough cleansing and debridement of open fractures, the provision of drainage by leaving the wound open, immobilization of the fracture and antibiotics. In most cases a combination of flucloxacillin and benzylpenicillin (or sodium fusidate), given 6-hourly for 48 hours, will suffice. If the wound is clearly contaminated, it is wise also to give metronidazole for 4 or 5 days to control both aerobic and anaerobic organisms. This is a viable treatment option and can lead to good results if the soft tissue and bone debridement is meticulous and complete and adequate vascularized and tension free soft tissue closure can be obtained; this may require advance soft tissue procedures such as local or free flaps. Clinical features the patient becomes feverish and develops pain and swelling over the fracture site; the wound is inflamed and there may be a seropurulent discharge. The presence of necrotic soft tissue and dead bone, together with a mixed bacterial flora, conspire against effective antibiotic control. Treatment requires soft tissue management and repeat debridement is required if there is evidence of inadequate debridement or infection. Traditionally it was recommended that stable implants (fixation plates and intramedullary nails) should be left in place until the fracture had united, and this advice is still respected in recognition of the adage that even worse than an infected fracture is an infected unstable fracture. However, advances in external fixation techniques have meant that almost all fractures can, if necessary, be securely fixed by that method, with the added advantage that the wound remains accessible for dressings and superficial debridement. If these measures fail, the management is essentially that of chronic osteomyelitis. The commonest of all predisposing factors is local trauma, such as an open fracture or a prolonged bone operation, especially if this involves the use of a foreign implant. Periprosthetic infection may evolve to chronic osteomyelitis and, due to its clinical relevance, will be addressed separately. Cavities containing pus and pieces of dead bone (sequestra) are surrounded by vascular tissue, and beyond that by areas of sclerosis ­ the result of chronic reactive new bone formation ­ which may take the form of a distinct bony sheath (involucrum). In the worst cases a sizeable length of the diaphysis may be devitalized and encased in a thick involucrum. Sequestra act as substrates for bacterial adhesion in much the same way as foreign implants, ensuring the persistence of infection until they are removed or discharged through perforations in the involucrum and sinuses that drain to the skin. A sinus may seal off for weeks or even months, giving the appearance of healing, only to reopen (or appear somewhere else) when the tissue tension rises. Bone destruction, and the increasingly brittle sclerosis, sometimes results in a pathological fracture. The histological picture is one of chronic inflammatory cell infiltration around areas of acellular bone or microscopic sequestra. The usual organisms (and with time there is always a mixed infection) are Staphylococcus aureus, Escherichia coli, Streptococcus pyogenes, Proteus mirabilis and Pseudomonas aeruginosa; in the presence of foreign implants Staphylococcus epidermidis (frequently coagulase negative staphylococcus), which is normally non-pathogenic, is the commonest of all. The host defences are inevitably compromised by the presence of scar formation, dead and dying bone around the focus of infection, poor penetration of new blood vessels and non-collapsing cavities in which microbes can thrive. Bacteria covered in a protein­polysaccharide slime (glycocalyx) that protects them from both the host defences and antibiotics have the ability to adhere to inert surfaces such as bone sequestra and metal implants, where they multiply and colonize the area. There is also evidence that bacteria can survive inside osteoblasts and osteocytes and be released when the cells die. In long-standing cases, the tissues are thickened and often puckered or folded inwards where a scar or sinus adheres to the underlying bone. Imaging X-ray examination will usually show bone resorption ­ either as a patchy loss of density or as frank excavation around an implant ­ with thickening and sclerosis of the surrounding bone. However, there are marked variations: there may be no more than localized loss of trabeculation, or an area of osteoporosis, or periosteal thickening; sequestra show up as unnaturally dense fragments, in contrast to the surrounding osteopaenic bone; sometimes the bone is crudely thickened and misshapen, resembling a tumour. The young boy (a) presented with draining sinuses at the site of a previous acute infection. Scanning with 67Ga-citrate or 111In-labelled leucocytes is said to be more specific for osteomyelitis; such scans could be useful for showing up hidden foci of infection, although its low specificity has led to limited use. Organisms cultured from discharging sinuses should be tested repeatedly for antibiotic sensitivity; with time, they often change their characteristics and become resistant to treatment. Note, however, that a superficial swab sample may not reflect the really persistent infection in the deeper tissues or may suffer from contamination; sampling from deeper tissues is crucial to understand the bone infection. The most effective antibiotic treatment can be applied only if the pathogenic organism is identified and tested for sensitivity. Unfortunately, standard bacterial cultures still give negative results in about 20% of cases of overt infection. However, although this has been shown to reveal unusual and otherwise undetected organisms in a significant percentage of cases, the technique is not widely available for routine testing. A range of other investigations may also be needed to confirm or exclude suspected systemic disorders (such as diabetes) that could influence the outcome. The system popularized by Cierny and colleagues in 2003 is based on both the local pathological anatomy and the host background (Table 2. The least serious, and most likely to benefit, are patients classified as Stage 1 or 2, Type A, i. Type B patients are somewhat compromised by a few local or systemic factors, but if the infection is localized and the bone still in continuity and stable (Stage 1­3) they have a reasonable chance of recovery. Type C patients are so severely 42 compromised that the prognosis is considered to be poor. Debridement At operation all infected soft tissue and dead or devitalized bone, as well as any infected implant, must be excised. The wound is inspected after 3 or 4 days and, if there are renewed signs of tissue death, the debridement may have to be repeated ­ several times if necessary. Porous antibiotic- impregnated beads can be laid in the cavity and left for 2 or 3 weeks and then replaced with cancellous bone grafts. Bone grafts have also been used on their own; in the Papineau technique the entire cavity is packed with small cancellous chips (preferably autogenous) mixed with an antibiotic and a fibrin sealant. Where possible, the area is covered by adjacent muscle and the skin wound is sutured without tension. An alternative approach is to employ a muscle flap transfer: in suitable sites a large wad of muscle, with its blood supply intact, can be mobilized and laid into the cavity; the surface is later covered with a split-skin graft. A free vascularized bone graft is considered to be a better option, provided the site is suitable and the appropriate facilities for microvascular surgery are available. This is especially useful if infection is associated with non-union after fracture. Soft-tissue cover Last but not least, the bone must be adequately covered with skin. For small defects, split thickness skin grafts may suffice; for larger wounds local musculocutaneous flaps, or free vascularized flaps, are needed. Aftercare Success is difficult to measure; a minute focus of infection might escape the therapeutic onslaught, only to flare into full-blown osteomyelitis many years later. Prognosis should always be guarded; local trauma must be avoided and any recurrence of symptoms, however slight, should be taken seriously and investigated. Yet bactericidal drugs are important (a) to suppress the infection and prevent its spread to healthy bone and (b) to control acute flares. The choice of antibiotic depends on microbiological studies, but the drug must be capable of penetrating sclerotic bone and should be non-toxic with long-term use. Antibiotics are administered for 4­6 weeks (starting from the beginning of treatment or the last debridement) before considering operative treatment. During this time, serum antibiotic concentrations should be measured at regular intervals to ensure that they are kept at several times the minimal bactericidal concentration. If surgical clearance fails, antibiotics should be continued for another 4 weeks before considering another attempt at full debridement. An acute abscess may need urgent incision and drainage, but this is only a temporary measure. The presence of a foreign implant may prompt surgical intervention to remove the implant, whether in case of internal fixation (plates, screws and intramedullary nails that may be substituted by external fixation until infection control) or substitution, as discussed below. When undertaking operative treatment, collaboration with a plastic surgeon is strongly recommended. With an incidence of about 1­2% in hip arthroplasty, 2­3% in knee arthroplasty, 1­2% in the shoulder and even 3­5% in the elbow, the economic impact may represent a 5- to 10-fold cost increase compared to a primary arthroplasty. Patient risk factors include obesity, diabetes, rheumatoid arthritis and immunosuppressive treatments. Other risk factors include previous surgery, perioperative infection at a distant site, allogeneic blood transfusion, prolonged operative time and postoperative complications, including hematoma, superficial surgical site infection, wound drainage, and wound dehiscence. Tsukayama and colleagues popularized a classification that included early postoperative infection, haematogenous infection, and late chronic infection, adding a fourth type with positive intraoperative culture in a patient with revision for presumed aseptic failure, although some of these may not be true infections.

It provides an overview of the complexity of the issues across systems, policies, practices, and beliefs, from the personal level to the population level. The resource section at the end of this chapter provides primary pediatric health care professionals with some current assets that may enable them to better achieve transition for their patients with developmentalbehavioral disorders or special health care needs, leading to improved outcomes for all involved. As a result of improvements in living conditions and medical advances over the last few decades, individuals with developmental-behavioral disorders have experienced an increase in life expectancy. Prior to these improvements, children with developmentalbehavioral disorders were primarily cared for by pediatric health care professionals in pediatric systems of health care. Across the United States, pediatric and adult health care systems vary tremendously with differences related to geography (eg, urban versus rural), affiliations with academic health systems and publicly funded systems, availability of care coordination supports, and access to insurance. Furthermore, the adult health care system differs from the pediatric system in structure (eg, availability of social work support) and processes (eg, shared decision making, roles of primary and specialty providers) as well as in experience and capacity to accept younger adults with certain childhood-onset conditions. All adolescents and young adults, regardless of disability status, who grow out of pediatric care transition to adult medical care; however, many may not have the knowledge and skills to navigate new adult care systems. In order to successfully transition to adult health care, adolescents and young adults need support and guidance from their families, referring pediatric providers, and accepting adult providers. They are at risk for lapses in primary and subspecialty care, increased emergency department utilization, poorer health outcomes, and worse quality of life. Guardianship is one example of a legal process to appoint a guardian for an individual deemed to have incapacitated decision-making capacity. All persons are deemed capable before the law until it can be demonstrated before a court that the person requires some supervision. Alternatives to full guardianship (eg, limited guardianship, representative payee, or power of attorney) exist and should be explored to guarantee that individuals with developmental disabilities retain as much autonomy as they are able. Primary pediatric health care professionals serving youth with developmental disabilities should 613 Chapter 26: Transition to Adult Medical Care be keenly aware of the need for guardianship determination by 18 years of age and should advise patients and families according to current state policy, practices, and procedures. Avoiding doing so could create a situation where a child without the ability to make medical decisions is in a vulnerable position, and his or her parents are blocked from participating until a court determination of guardianship is established. Each of these groups has specific roles and responsibilities to promote a successful transition process. As adolescents with developmental-behavioral disorders transition to adult care, it is especially important for them to feel that clinicians maintain respect for their personal autonomy. Even though this goal is universal across different patient populations, it is especially important for young adults with known cognitive disabilities that their health care professionals presume that they possess decision-making capacity. Health care professionals can help this process by becoming more knowledgeable about these issues and achieving better practice though specific training in interviewing and examination to both assess decision-making capacity and support the autonomy of patients with developmental-behavioral disorders. However, because individuals with developmental-behavioral disorders experience unique risks during their time as adolescents and into adulthood, their parents have unique tensions to resolve. Primary pediatric health care professionals want to find knowledgeable and compatible adult health care professionals who are willing to accept patients with developmentalbehavioral disorders. Adult health care professionals who accept these patients want to provide quality care for a patient population with whom they are likely less familiar. There are at least 2 major types of barriers for individuals with developmental-behavioral disorders that stand in the way to successful transitions. The first category of barrier is institutional and administrative, and the second is attitudinal. Both types of barriers are important, and they also frequently interact dynamically. Lack of adequate reimbursement for the often time-consuming and difficult tasks of care management leads either to health care teams that are struggling to stay financially viable if they try to offer this important portion of care or to health care teams that limit or entirely avoid accepting patients with significant developmental-behavioral disorders into their practices. If an adult payer (ie, insurance company) carves out all Chapter 5 codes, it may be extremely difficult for patients with developmental conditions to have their medical care covered. Primary care providers increasingly refer these patients to subspecialists because they cannot offer this care within the business constraints that are part of the current fee-for-service model. It is hoped that a transition to value-based models will result in a meaningful increase in the payments for health care management, but this is far from certain and still in the future. The second set of barriers to successful transition is attitudes that can be divided into 3 groups: those of families, those of the individuals themselves, and those of health care professionals. First, parents of individuals with developmental-behavioral disorders may find it difficult to let go of their trusted pediatric providers and institutions with whom 615 Chapter 26: Transition to Adult Medical Care they often have longstanding relationships. Building new trusting relationships with new adult providers and systems is difficult. However, this tension is particularly acute for parents of children with developmental-behavioral disorders. Their children have to navigate an inherently more complex transition, their children are frequently less personally able to make the transition without significant supports, and parents have usually been the ones to supply the majority of that support. Especially for children with cognitive impairments, behavioral and mental health concerns, or significantly life-threatening medical conditions, families are reasonably reluctant to trust systems that they have too often experienced as broken, unreliable, and not up to the task of supporting their loved ones. The second group of attitude barriers can be found in individuals with developmentalbehavioral disorders who are in the state of not knowing what is possible. One common example of this occurs when adult individuals with developmental-behavioral disorders are not aware that they have a right to privacy and are specifically not aware that their parents do not have to continue to accompany them into the exam room at medical clinic visits. Finally, like families, pediatric health care professionals who have served children with developmental-behavioral disorders have worries about their patients, and these worries (again, like those of families) are often based in lived experiences, especially related to the care of children with cognitive impairments, behavioral/mental health concerns, or significantly life-threatening medical conditions. Pediatric health care professionals are well aware of the lack of support for these children, their families, and themselves. They are also aware that there may be no clear protocols or systems to help identify adult health care professionals who accept transitioning patients. The majority of referring and receiving health care providers have limited knowledge about the adult life outcomes of individuals with developmental-behavioral disorders, which impacts how they care for patients. For example, many are unaware or lack confidence in explaining the tremendous improvements in the function and life expectancy of individuals with Down syndrome and may therefore not explore the issues of sexuality, dating, marriage, driving, employment, mental health, or other topics that they routinely discuss with other adolescents and young adults. Additional System-Level Challenges As currently structured, funding sources create systematic barriers. Frequently, there are changes in sources and eligibility criteria for health care funding that can occur when a person ages out of some programs and into others. For example, until 21 years of age, the federal government mandates what is covered as Medicaid supported services; after 616 American Academy of Pediatrics Developmental and Behavioral Pediatrics 21 years of age, states determine what services they will offer. In addition, state waiver services may change for those older than 21 years, or access may be dependent on early application owing to long wait lists. Waivers are state programs that provide supports for individuals who meet an institutional level of care through Medicaid home and community-based services and are also referred to as 1915(c) programs. Although developmental-behavioral disorders are the most prevalent chronic medical disorders encountered in pediatric medicine (see Chapter 1, Child Development: the Basic Science of Pediatrics), subspecialty-level pediatric providers are scarce, and equivalent subspecialty-level adult health care providers are nonexistent. Of the 118,292 pediatricians currently certified by the American Board of Pediatrics, only 775 are subspecialty board­certified in Developmental-Behavioral Pediatrics, and only 255 are subspecialty board­certified in Neurodevelopmental Disabilities. These few pediatric physicians are trained specifically in the many varied areas related to the long-term care of children with developmental-behavioral disorders, including developmental outcomes, educational policy, coordination of care, family systems dynamics, and governmental services and supports. Training and board certification in internal medicine does not have a single learning objective specifically directed toward developmental-behavioral disorders, so internal medicine physicians have reason to wonder whether they have the appropriate training to care for this important and growing population of adults. Not only does the lack of an equivalent adult subspecialty have significant clinical effects; it also affects at least 3 pernicious structural problems: (1) the shape and content of medical school curricula are usually entirely lacking in any competencies specifically related to developmental-behavioral disorders across the lifespan, (2) the shape and direction of research programs rarely are driven by questions about the medical and social problems of developmental-behavioral disorders, and (3) the shape and advocacy initiatives directed toward addressing population health and public policy programs rarely address the unique needs of developmental-behavioral disorders. For instance, although educational programs often take into account language and cultural barriers, 617 Chapter 26: Transition to Adult Medical Care they almost never take into account barriers due to intellectual disability, autism, or other developmental-behavioral disorders. Another example is found in the lack of appropriate equipment designed for examination rooms or radiology suites to accommodate an individual who uses a wheelchair for mobility. All of these problems stem from the simple fact that on most medical school committees, research review committees, agency boards, and public health councils, there is no one present with any "skin in the game" relative to developmental-behavioral disorders. While many health systems have developed transition programs for cystic fibrosis, congenital heart disease, sickle cell disease, and inflammatory bowel disease, these same health systems have not given the same institutional support for transitional programs for individuals with developmental-behavioral disorders. This disparity may be attributable in large part to the availability of adult pulmonologists, cardiologists, hematologists, and gastroenterologists versus the lack of adult specialists in developmental-behavioral disorders. There are several areas of possible intervention that have great potential for improving the number of individuals with developmental-behavioral disorders who successfully transition from pediatric to adult health care systems. These areas of advancing highquality medical home practice include care coordination activities, medical and postgraduate education reforms, health care financing changes, public health education initiatives, and innovative research funding programs. There have been successful initiatives to increase the formal training and general awareness of previously underrepresented issues within medical school curricula (eg, efforts to improve knowledge, skills, and attitudes related to lesbian, gay, bisexual, transgender, and questioning individuals and potential medical issues), and these prior experiences point to the potential for a similar initiative for individuals with developmental-behavioral disorders, especially including transition as a specific issue to be addressed. Deliberate placement of medical students and residents into clinical settings where quality medical homes provide care coordination should be encouraged. Further, there will need to be an exploration of the creation of an adult medicine subspecialty that is dedicated to the care of individuals with developmental-behavioral disorders. These educational initiatives have the potential to transform the attitudes of clinicians in a way that moves transitions from being an afterthought to a central organizing principle in their care of these patients. These initiatives will, of course, require the infusion of new financial and administrative resources. Without clear and effective changes to the current payment systems, which undervalue the time and work of care coordination (including that needed for successful transitions), no amount of educational programs will be generally effective-if clinical teams are not reimbursed at least enough to adequately pay for their time, there will not be effective systemic change. The power of these programs cannot be underestimated in creating a true paradigm shift in the attitudes of the general public as well as the treating clinicians.

In recent years it has spread more widely in Europe but it is rarely encountered south of the equator. Sickle-cell disease is most likely in homozygous offspring (those with HbS genes from both mother and father), but it may also occur in heterozygous children with HbS/C haemoglobinopathy and HbS/ thalassaemia. Inheritance of one HbS gene and one normal -globin gene confers the (heterozygous) sickle-cell trait; HbS concentration is low and sickling occurs only under conditions of hypoxia. In the established disorder, the main clinical features are due to a combination of chronic haemolytic anaemia and a tendency to clumping of the sickle-shaped cells which results in diminished capillary flow and recurrent episodes of intracapillary thrombosis. Secondary changes such as trabecular coarsening, infarctions of the marrow, periostitis and osteonecrosis are common. Complications include hyperuricaemia (due to increased red cell turnover) and an increased susceptibility to bacterial infection. Clinical features Children during the first two years of life may present with swelling of the hands and feet. In older children a typical feature is recurrent episodes of severe pain, sometimes associated with fever. Other bone changes are due to a combination of marrow hyperplasia and medullary infarctions. Instead of having an X in the Hb beta chain, the replacement of this residue with Y results in Hb precipitation at low oxygen tensions. In deoxygenated blood there is increased aggregation of the haemoglobin molecules and distortion of the red cells, which become somewhat sickle-shaped. At first this is reversible and the cells reacquire their normal shape when the blood is oxygenated. Eventually, however, the red cell membrane becomes damaged and the cells are permanently deformed. The sickle-cell trait, which originated in West and Central Africa centuries ago, is an example of natural selection for survival in areas where malaria was endemic. Anaesthesia carries definite risks; failure to maintain adequate oxygenation may recipitate vascular occlusion in the central nervous system, lungs or kidneys. Prophylactic antibiotics are advisable as the risk of postoperative infection is high. Under increased air pressure the blood and other tissues (especially fat) become supersaturated with nitrogen; if decompression is too rapid, the gas is released as bubbles, which cause local tissue damage, generalized embolic phenomena and intracapillary coagulation. Prolonged compression may also cause swelling of marrow fat cells and decreased intramedullary blood flow, possibly due to oxygen toxicity. In the most acute cases there can be circulatory and respiratory collapse, severe neurological changes, coma and death. Management the aim is prevention; the incidence of osteonecrosis is proportional to the working pressure, the length of exposure, the rate of decompression and the number of exposures. Strict enforcement of suitable working schedules has reduced the risks considerably. Trabecular coarsening and thickening of the cortices may be mistaken for signs of infection. Bacterial osteomyelitis and septic arthritis, sometimes involving multiple sites, are serious complications, particularly in children. Treatment A follow-up study of untreated children with femoral head necrosis due to sickle-cell disease showed that 80% of them had permanently damaged hips with severe loss of function. If episodes of bone pain are frequent, transfusions may be necessary to reduce the concentration of HbS. During a crisis, the patient should be given adequate analgesia and should be kept fully oxygenated. Infections should be guarded against, or treated promptly with the appropriate antibiotics. The hip is most frequently affected, but lesions also appear in the distal femur, the talus and the head of the humerus. Bone ischaemia is usually attributed to the increase in medullary cell volume and sinusoidal compression, but it is likely that other effects (abnormal cell emboli and increased blood viscosity) are equally important. This is due to the combined effects of damage to small blood vessels, marrow cells and bone cells. Such changes, which are dose-related, often occurred in the past when low-energy radiation was in use. Nowadays, with megavoltage apparatus and more sophisticated planning techniques, longterm bone damage is much less likely; patients who present with osteonecrosis are usually those who were treated some years ago. Areas affected are mainly the shoulder and ribs (after external irradiation for breast cancer), the sacrum, pelvis and hip (after irradiation of pelvic lesions) and the jaws (after treatment of tumours around the head and neck). There is a tendency for the Gaucher deposits to become infected and the patient may present with septicaemia. A diagnostic, though inconstant, finding is a raised serum acid phosphatase level. Pathology Unlike the common forms of ischaemic necrosis, which always involve subchondral bone, radiation necrosis is more diffuse and the effects more variable. Marrow and bone cells die, but for months or even years there may be no structural change in the bone. The management of established osteonecrosis follows the principles outlined earlier. However, there is a greater risk of infection following operation and suitable precautions should be taken. The surrounding bone is usually osteoporotic; in the jaw, infection may follow tooth extraction. Clinical features the patient usually presents with pain around the shoulder, the hip, the sacrum or the pubic symphysis. There will always be a history of previous treatment by ionizing radiation, though this may not come to light unless appropriate questions are asked. There may be local signs of irradiation, such as skin pigmentation, and the area is usually tender. Treatment Treatment depends on the site of osteonecrosis, the quality of the surrounding bone and the life expectancy of the patient. Nevertheless, if pain cannot be adequately controlled, and if the patient has a reasonable life expectancy, joint replacement is justified. The affected area shows many of the features of ischaemic necrosis, including death of bone cells in the osteoarticular fragment and reactive vascularity and osteogenesis in the surrounding bone. The disorder occurs mainly in adolescents and young adults, often during phases of increased physical activity, and it may be initiated by trauma or repetitive stress. Impact injuries can cause oedema or bleeding in the subarticular bone, resulting in capillary compression or thrombosis and localized ischaemia. If the crack fails to unite, the isolated fragment may lose its blood supply and become necrotic. However, it is thought that there must be other predisposing factors, for the condition is sometimes multifocal and sometimes runs in families. This occurs typically in young adults, usually men, and affects particular sites: the inner (medial) surface of the medial femoral condyle in the knee, the anteromedial corner of the talus in the ankle, the superomedial part of the femoral head, the humeral capitulum and the head of the second metatarsal bone. One year later he developed pain in the left hip and X-ray showed (a) a fracture of the acetabulum. Diagnosis of radiation necrosis was confirmed when (b) the fracture failed to heal and the joint crumbled. The most common sites are (a) the medial femoral condyle, (b) the talus and (c) the capitulum. Treatment Treatment in the early stage consists of load reduction and restriction of activity. For a large joint such as the knee, it is generally recommended that partially detached fragments be pinned back in position after roughening of the base, while completely detached fragments should be pinned back only if they are fairly large and completely preserved. If the fragment becomes detached and causes symptoms, it should be fixed back in position or else completely removed. Treatment of osteochondrosis at the elbow, wrist and metatarsal head is discussed in the relevant chapters. It is now recognized that the condition can occur in patients of either sex and at all ages from late adolescence onwards. The issue is important because transient osteoporosis has until now been regarded as a reversible disorder which requires only symptomatic treatment while osteonecrosis often calls for operative intervention.

Clinical features arise from both systemic responses to changes in mineral exchange and local effects of abnormal bone structure and composition. Bone formation in the cartilaginous model progresses along the diaphysis but the epiphyseal ends remain unossified until after birth. The entire sequence has been aptly summarized as condensation chondrification ossification. Soon after birth secondary ossification centres begin to appear in the still cartilaginous ends of the tubular bones, a process that will occur during childhood in all the endochondral bones (bones formed in cartilage). By then each bone end is defined as an epiphysis, the growth plate between the epiphysis and the rest of the bone as the physis, the adjacent end of the long bone the metaphysis, and the shaft as the diaphysis. Longitudinal growth continues up until late adolescence, by a process of endochondral bone formation, whereby cartilage formed beneath the growth plate becomes calcified to produce the primary spongiosa, which is then replaced by the secondary spongiosa following vascular invasion. Cessation of longitudinal growth is heralded by the growth plate becoming ossified, resulting in fusion of the epiphysis to the metaphysis. An increase in bone circumference occurs by a different process, namely periosteal bone formation. The latter involves small generative cuboidal cells in the deepest layer of the periosteum. In contrast to longitudinal growth, periosteal bone formation does not involve the intermediary formation of cartilage. Whereas longitudinal growth ceases once growth plates have fused, periosteal bone formation may continue life-long, depending on the anatomical site. Diarthrodial joints (freely movable, synovial joints) comprise hyaline cartilage, which is ideally suited to permit low-friction movement and to accommodate both compressive and tensile forces. Embryonic development of the limbs begins with the appearance of the arm buds at about 4 weeks from ovulation and the leg buds shortly afterwards. These at first have the appearance of miniature paddles but by around 5 weeks the finger and toe rays become differentiated. By then primitive skeletal elements and pre-muscle masses have begun to differentiate in the limbs. From about 6 weeks after ovulation the primitive cartilaginous bone-models start to become vascularized and primary ossification centres appear in the chondroid anlage. They support every part of the body in a wide variety of positions and load-bearing; they protect important soft tissues such as the brain, the spinal cord, the heart and the lungs; they provide space and structural support for cells involved in haematopoiesis; and they act as jointed levers that facilitate a range of movements. Bone as tissue has an equally important role as a mineral reservoir which helps to regulate the composition ­ and in particular the calcium ion concentration ­ of the extracellular fluid. For all its solidity, it is in a continuous state of flux, its internal shape and structure changing from moment to moment in concert with the normal variations in mechanical function and mineral exchange. All modulations in bone structure and composition are brought about by cellular activity, which is regulated by hormones and local factors; these agents, in turn, are controlled by alterations in mineral ion concentrations. Disruption of this complex interactive system results in systemic changes in mineral metabolism and generalized skeletal abnormalities. The matrix Type I collagen fibres, derived from tropocollagen molecules produced by osteoblasts, make up over 80% of the unmineralized matrix. They consist of collagen fibrils comprising a triple helix, with the overall structure stabilised by cross-linking between adjacent fibrils. It also serves as a scaffold on which the mineral component ­ crystalline hydroxyapatite ­ is deposited. Their functions have not been fully elucidated but they appear to be involved in the regulation of bone cells and matrix mineralization. Osteocalcin is produced only by osteoblasts and its concentration in the blood is, to some extent, a measure of osteoblastic activity. The interface between bone and osteoid can be labelled by administering tetracycline, which is taken up avidly in newly mineralized bone and shows as a fluorescent band on ultraviolet light microscopy. In mature bone the proportions of calcium and phosphate are constant and the molecule is firmly bound to collagen. While the collagenous component lends tensile strength to bone, the crystalline mineral enhances its ability to resist compression. Unmineralized matrix is known as osteoid; in normal life it is seen only as a thin layer on surfaces where active new bone formation is taking place, but the proportion of osteoid to mineralized bone increases significantly in rickets and osteomalacia. These two types of cell, working in concert, continuously remodel the internal bone structure. Lying in their bony lacunae, they communicate with each other and with the surface lining cells by slender cytoplasmic processes. They are sensitive to mechanical stimuli and communicate information and changes in stress and strain to the active osteoblasts (Skerry et al. Osteoclasts these large multinucleated cells are the principal mediators of bone resorption. They develop from mononuclear precursors in the haemapoietic marrow (the same lineage as macrophages) under the influence of local osteoblastic stromal cells Bone cells There are of three types of bone cell: osteoblasts, osteocytes and osteoclasts. Osteoblasts Osteoblasts are concerned with bone formation and osteoclast activation. They are derived from mesenchymal precursors in the bone marrow and the deep layer of the periosteum. Mature osteoclasts have a foamy appearance, due to the presence of numerous vesicles in the cytoplasm.
